Which represents a short-term storage for carbon?
A Coral reefs formed from calcium carbonate.
B. Coal formed from plants that lived long age
C. Limestone rocks quarried at Earth's surface.
D. Carbohydrates stored in fruits and vegetables.

Answers

Carbohydrates stored in fruits and vegetables represent the short-term storage for carbon.

What is Carbon?

Carbon is a chemical element that is very abundant on the surface of the earth. It exists in nature in its pure forms like Graphite and diamond. It is also required for plants and animals to perform their metabolic activities with the addition of certain other compounds.

Carbon compounds are held for the shortest amount of time in fruits and vegetation.

Therefore, Carbohydrates stored in fruits and vegetables represent the short-term storage for carbon.

Which of the following events occurs directly AFTER a DNA molecule is unzipped?

Answers

Answer:

DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).

Explanation:

Which of the following events occurs directly after RNA polymerase recognizes the transcription start site of a gene? the DNA strand begins to unwind, separating the two strands.

Blue Genotype BB Yellow Genotype YY What would be the Genotype for Blue and Yellow? A. BY, or YB B. GG C. Not Possible D. BuYe

Answers

Answer:

A. BY, or YB

Explanation:

This question is depicting a phenomenon in inheritance called CODOMINANCE, which is a type of non-mendelian inheritance in which two alleles of a gene both express themselves in that gene. In this question, the allele for blue color (B) is codominant with the allele for yellow color (Y).

This means that an individual that has a blue phenotype will possess the genotype BB while an individual that has a yellow phenotype will possess the genotype YY. Hence, in an heterozygous state in which both alleles combine to produce a simultaneous blue and yellow phenotype, the genotype will be BY or YB.

How do owls relate to biotechnology?

Answers

Answer:

Owls hunt throughout the night in deserted places such as cemeteries, run-down farms, and other open areas. The diet of many owls consists mainly of rodents and other small animals. Prey is usually eaten whole, but the whole prey is not digested. An owl's digestive tract compresses the undigested portions of the prey, such as fur and bone, into a compact pellet that the owl coughs up and expels through its mouth.

what 2 parts of a chlorplast does photosynthesis take place

Answers

Answer:

The Grana and The Stroma.

Explanation:

I hope this helps u! :D

Answer: Photosynthesis occurs in geranium and stroma parts of chloroplast.

Explanation:

Chloroplast is an organelle covered by double membrane. Inner membrane is folded inside to form lamellae. The lamellae are stacked one above the other to from geranium. There are many grana in a single chloroplast. The remaining matrix consisting of cytoplasm is termed stroma. In the stroma are present other cytoplasmic inclusions like fragments of DNA and ribosome, etc.

Photosynthesis occurs in 2 steps:

1. Hill's reaction or Light reaction: It occurs in presence of light in geranium part of chloroplast.

2. Dark reaction or Blackmann's reaction: It does not require light directly, occurring irrespective of presence or absence of light. However, it is dependent upon the end products of light reaction. it occurs in stroma part of chloroplast.

The answer may be supplemented by viewing the diagram of electron microscopic structure of chloroplast from any book one may have, covering photosynthesis.

If the enzyme DNA helicase was denatured, what would be the immediate effect on DNA replication?

A) New nucleotides would not be added to the growing strand
B) original DNA strands would not be separated
C) sections of new DNA in the lagging strand could not be connected
D) DNA mutation rate would increase dramatically

Answers

If the enzyme DNA helicase was denatured, then original DNA strands would not be separated (Option B).

DNA helicase is a key enzyme that unwinds both DNA strands during DNA replication.

In consequence, there would be no replication fork if this enzyme helicase) is denatured.

DNA polymerase is the enzyme required to add new nucleotides to the growing DNA strands.

In conclusion, if the enzyme DNA helicase was denatured, then original DNA strands would not be separated (Option B).
